Great question — SB326 inspections (balcony/deck inspections for multifamily housing in California) are a big deal, and unfortunately, not every company advertising them is legitimate. The biggest red flag consumers should watch for is:

🚩 If the company performing inspections also performs repairs.

Here’s why:

Conflict of interest – The law (SB326/SB721) was designed so that inspections are objective and not influenced by profit motives from repair work. If the same company inspects and repairs, they may be financially motivated to exaggerate problems or recommend unnecessary work.

At William Leys Waterproofing Consultants LLC we guarantee in writing that we do not have any conflicts of interest. 

🚩 Compliance issues – The statute is clear: inspections must be done by a licensed architect, structural engineer, or a qualified building inspector who is not associated with a repair contractor. If someone is offering both, they may not be following the law.


Other red flags to watch for:

🚩No license disclosure (can’t prove they’re an architect, engineer, or building inspector). Who will be inspecting? An engineer or architect, or just some random people who may not be qualified in any way shape or form.

At William Leys Waterproofing Consultants LLC we guarantee that a structural engineer that we partner with will perform the physical inspection. Some companies flirt with danger by hiring subcontractors who do the inspection, and then those companies have an engineer robo sign your report.

🚩 Low-ball pricing far below market rates — often a sign they’re using inspections as a “loss leader” to sell repair work.

This is exactly right, and that’s what they are doing. We’ve done second inspections for clients and they were very happy to learn that the repairs the other company said had to be done in an emergency basis was exaggerated.

🚩Vague or incomplete reports — a proper SB326 inspection requires documented findings, photographs, and repair recommendations (if needed).

🚩 High pressure sales tactics — pushing you to sign a repair contract right after the inspection.


👉 Bottom line: Choose an independent, inspection-only professional who has no stake in whether repairs are needed. That independence is what protects you and your HOA from unnecessary costs.
